Ashley Tisdale and Simon Rex have different credits to their comedic resumes, but both seem ideal for the latest incarnation of “Scary Movie.” While Tisdale is the idol of kids, tweens, and more than a few adults with her weekly portrayal of Candace Flynn on the Disney Channel animated series “Phineas and Ferb,” Simon is a veteran of the franchise, having starred in the last two installments. The pair recently sat down with Bullz-Eye to discuss “Scary Movie 5,” the latest chapter of the comedy series, featuring parodies of films like “Mama” and “Paranormal Activity,” as well as non-horror movies like “Rise of the Planet of the Apes” and “Black Swan.”

BULLZ-EYE: When did you guys get to see “Mama,” which is the main plot of the movie?

ASHLEY TISDALE: I saw it opening weekend, just because I wanted to go see the movie.

SIMON REX: Then, we went and saw it together.

ASHLEY TISDALE: I came out of the theaters and texted the producers and said, “We should be spoofing ‘Mama’ because it works so well.” Then, Phil [Beauman] said, “We’re actually going to spoof ‘Mama’.”

BE: How much did the additional “Mama” shooting entail?

ASHLEY TISDALE: A lot. About 60 percent (laughs).

SIMON REX: We shot for about a 10-day reshoot when we got back to L.A.

ASHLEY TISDALE: It was a lot of work with really long days.

SIMON REX: We had to update it. The movies we spoofed were already a year or two old. “Black Swan” wasn’t really a horror movie. “Rise of the Planet of the Apes” wasn’t really a horror movie, so it needed some current horror stuff. With “Evil Dead,” which isn’t even out yet, we spoofed the trailer.

BE: Are either of you horror fans?

SIMON REX: I’m more of a fan of the comedy genre or spoofs like this, from Mel Brooks to all of David Zucker’s movies. I am a fan of what we did more than horror movies.

ASHLEY TISDALE: I’ve always been scared of scary movies, because I live by myself. Seeing something and having a big imagination, I’ll think someone is there. It’s funny — this movie has made me like them. Now, I’ll go see “Mama,” because now I’ll see things and think, “That is so spoofable.”

BE: Ashley, when you’re humping the microwave, are you thinking, “This is comedy gold”?

ASHLEY TISDALE: No. (laughs) That was part of the reshoots. I had already humped a potted plant and that was nerve-wracking. There was only one camera guy and they kept it really quiet. When it got to the point with the chair and the microwave, I was like, “Oh, I’ve got this. It’s fine that everybody’s watching.” I do remember the hardwood chair hitting me from behind and I looked from behind like I was all into it. Simon was like, “You’re getting slammed by a chair right now.” And I just started hysterically laughing. It was one of those moments where you never think you’re going to be in that position.
